Kube-Logging-Operator-Fluentd Overview

Secure your stack with a hardened Kube-Logging-Operator-Fluentd image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Kube-Logging-Operator-Fluentd is the Fluentd build that Kube-Logging-Operator deploys as its log aggregator, receiving logs forwarded by Fluent Bit collectors and routing them onward. It ships with output plugins for common destinations already installed — Elasticsearch, Loki, S3, GCS, Kafka, Splunk, CloudWatch Logs, and others — so platform teams can send logs to the systems they already use without building and maintaining a custom Fluentd image. The Logging Operator swaps this image in through the Logging custom resource's spec.fluentd.image field, so hardening the aggregator doesn't require changing how flows and outputs are configured.

Try It Out

In your project directory, save the code below to a file named demo.conf. This file is used to catch and parse log strings received by Fluentd:

<source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

<match **>
  @type stdout
</match>

Run the following from the project directory, to initiate a Fluentd container and listen for incoming log strings:

docker run --rm -it \
-p 24224:24224 \
-v $(pwd)/demo.conf:/fluentd/etc/conf.d/demo.conf \
reg.mini.dev/kube-logging-operator-fluentd

Leave this terminal open. We will use it to monitor incoming log strings.

Initiate a BusyBox container and send the message "Hello Fluentd" to the Fluentd logging monitor:

docker run --rm \
--name hello-fluentd \
--log-driver=fluentd \
reg.mini.dev/busybox:latest echo "Hello Fluentd"

The Fluentd terminal should log an incoming string, such as:

2026-08-16 12:28:41.000000000 +0000 c0f9584c935e: {"log":"Hello Fluentd","container_id":"c0f9584***","container_name":"/hello-fluentd","source":"stdout"}

Refer to the Kube-Logging-Operator image for deployment instructions.

Technical Considerations

The Kube-Logging-Operator-Fluentd image provided by Minimus is a slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.

Kube-Logging-Operator-Fluentd built by Minimus:

Ships with output plugins for Elasticsearch, Loki, S3, GCS, Kafka, Splunk, CloudWatch Logs, and more pre-installed.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.
